of the hide or skin from the tables, and es- @I The separator g starts or loosens the side of pecially those which stick thereto, a device is .i the hide or skin from one side of the table,

and provision is also made for starting or loosening the other side of the hide or skin this purpose I have shown one form of mechanism which consists of a bar or plate 2O (see Fig. 3) extended transversely of the table and secured to cranks or arms 21 which is supported by rods 23, arranged to slide in suitable supports, shown as brackets 24 attached to the framework ofthe machine, the rods 23 being encircled by s prings 25 and j on a rod 22,

having their front ends connected to the rod 22. The spring 25 acts to normally keep the push baror plate 2O in its inactive or inoperative position out of the path of movement of the tables and the endless carrier.

The push-bar 20 is moved forward bylevers 27, pivoted at v28 to the framework and havj ing their upper ends forked'to straddle the rod 22 and having their lower ends provided with rollers 30, which are engaged by suitable cams or projections 31 on the endless carrier. The cams 31 are suitably shaped and appropriately located with relation to the tables, so as to engage the levers 27 at or about the time the upper end or top of the table has been brought substantially opposite to or in a horizontal line with the push` bar 2O and thereby cause said levers to have their upper ends moved toward the path of movement of the table.

It is preferred to have the cams move the bar 20 across and beyond the path of movement of the tables, so that the hide or skin will be loosened or started away from the opposite side of the table suhiciently to permit it to be removed therefrom by the deliveryrolls and carried away by the endless band or apron. The cams 31 may be made of sulH- cient length to remain in engagement with the levers 27 until the hide or skin has been disengaged from the opposite side of the table;

ut to avoid making the cams of suflicient length to accomplish this purpose it is preferred to provide means for locking the levers 27 in their forward or operative position, so that the cams 31 may be made short and only long enough to move the levers 27 into their operative position, and when in this position said cams may pass out of engagement with the levers 27, which are retained in their oper ative position by latches 90, (see Figs. 3 and 6,) pivoted at 91 to the side frames d, and each having a hook 92, which is designed to engage the bar 22 when the latter is in its forward or operative position. (Shown in Fig. 6

position until the hook 92 of the latch is disengaged from the bar 22. This may be effected by a suitable cam or projection 93 on the endless carrier engaging a lever 94, pivoted at 95 to a stationary part of the frame The push-bar 20 is thus held in its operative (i 1 and having its arm 96 provided with a lug or projection 97, latch rests.

upon which a nger 9S of the By reference to Figs. 3 and 6, it l from the opposite side of the table, and for ,i i l will be seen that when the release camv or projection 93 strikes the lever 94 on the downward movement of the endless carrier the said lever is turned on its pivot and its arm 96 is elevated, which carries with it tl ic linger 98, thereby turning upward the latch 90 and disengaging the latch 90 from the rod 95, which is then returned to its normal or inoperative position by the spring 25. The hide or skin thus loosened from the table a is carried away by the endless band or apron, which is moved in the direction indicated by the arrow 35 in Fig. 2, and the front end otI the hide or skin passes oh from the endless band and descends on one side of a vertically-arranged support or assembling device, which may be made as herein shown, and consists of a cross-bar 40, secured at its ends to upright levers 41, which are pivoted at their lower end, as at 42. The levers 41 normallyv occupy a substantially vertical position with the bar substantially in line with the roller 12 and are adapted to be antonlatieally turned backward or outward in the direction indicated by the arrow 140 in Fig. 2 until the cross-bar 40 has been brought to a position beyond the roller 12, as will leave sullicient space between said roller and said bar, to permit a portion of the hide or skin to pass down on the other side of the cross-bar 4-0.

The rocking or tilting movement of the cross-bar 40 just described may be ell'ected, as herein shown, by cam-disks, fast on a rotatable shaft 51 and acting on projccti ons or arms 52 on the levers 41. The cams 50 are suitably shaped to permit springs .54j to hold the levers 41 in a substantially vertical position while substantially one-hall of the hide or skin is passing down on the outer side ol' the cross-bar 40 and then to .move said levers backward, so as to permit the remaining portion of the hide or skin as it leaves the endless carrier or apron 10 to pass down on the other side of the cross-bar 40. In this manner one or any number of hides or skins within limits may be assembled or hung on the movable support in convenient position for removal by the operator.

The endless carrier or apron 10 may have cooperating with it a device shown as an upright board or plate 56 suitably secured to the framework of the machine and which serves to dellect the free end of the hide or skin passing off of the delivery carrier or apron 10 down on one side of the supporting crossbar 40. The assembling device referred to is designed to be intermittently operated. which may be accomplished, as herein shown, by one or more projections or devices 6() on a link chain 61 engaging one or more teeth or projections 62 on a disk 63, which fast on the shaft 5l carrying the cam .50, the link chain 61 passing over a sprocket-wheel 65 on the shaft 13 and about a sprocketwheel 66 on the cam-shaft 51.
